Create a trail effect (Meteor)
With current experimental build 2.91 you can base this on Volume Object.

create the shape from a Mesh Object.
add Volume Object and in modifiers choose Mesh to Volume, as source Object choose created shape one
add Point Light object in trail direction (close to a sphere)




With second modifier Volume Displace you can use texture to distort. Here is a few examples of Cloud texture (variations in texture properties level).


Since I don't see an option to animate Texture position (for now) for Volume Displace modifier, here is a basic node material ...



With additional Curve modifier (for mesh Trail) or Wiggle bones you would be able to animate motion in more natural way (like a flame moved from one place to another).
